    James Hansen issued dire warnings in the summer of 1988. Today earth is only modestly warmer. James E. Hansen wiped sweat from his brow. Outside it was a record-high 98 degrees on June 23, 1988, as the NASA scientist testified before the Senate Committee on Energy and Natural Resources during a prolonged heat wave, which he decided to cast as a climate event of cosmic significance. He expressed to the senators his “high degree of confidence” in “a cause-and-effect relationship between the greenhouse effect and observed warming.” With that testimony and an accompanying paper in the Journal of Geophysical Research,...

    In a NASA town hall yesterday (May 17), NASA's new administrator, Jim Bridenstine, said that he knows Earth's climate is changing, and that humans contribute to it "in a major way," also supporting NASA's research into that important area. The statement is significant because Bridenstine has expressed doubt about human-caused climate change in the past, causing some to question his suitability to lead a fact-focused NASA. In 2013, as an Oklahoma congressman, Bridenstine claimed there was no current trend toward global warming. More recently, such as in his NASA administrator confirmation hearings last November, he has acknowledged that human activity...

    The demonization of the “miracle molecule,” carbon dioxide, continued last week with the announcement that its concentration had reached 410 parts per million (ppm). Nearly all reporting of this noted that this was the highest level in 800,000 years and predicted a host of associated climate calamities. While the current concentration of this vital gas is about 40% higher than at the start of the Industrial Revolution, unreported is that Earth has been suffering from steadily decreasing and perilously low concentrations of CO2. Until the consumption of fossil fuels began liberating this important gas from ancient rocks , the Earth...

    Concrete is one of the most widely used building materials in the world, but it also is responsible for about 5% of all global carbon dioxide emissions according to the Earth Institute at Columbia University. Those emissions result directly from the conversion of limestone into cement and indirectly by burning fuel to heat the limestone to 1400º C, the temperature required to initiate the conversion process. “Cement manufacturing is highly energy and emissions intensive because of the extreme heat required to produce it. Producing a ton of cement requires 4.7 million BTU of energy, equivalent to about 400 pounds of...

    Enzymatic liquid membrane design and mechanism of carbon dioxide capture and separation. The Sandia/University of New Mexico membrane is fabricated by formation of 8-nanometer diameter mesopores. Using atomic layer deposition and oxygen plasma processing, the silica mesopores are engineered to be hydrophobic except for an 18-nm-deep region at the pore surface which is hydrophilic. Through capillary condensation, carbonic anhydrase enzymes and water spontaneously fill the hydrophilic mesopores to form an array of stabilized enzymes with an effective concentration greater than 10 times of that achievable in solution. These catalyze the capture and dissolution of carbon dioxide at the upstream surface...

    In a bizarre irony, the German daily newspaper Die Welt has proclaimed U.S. President Donald Trump “the most successful climate protector in the world” after a new global climate report revealed that U.S. carbon dioxide emissions dropped dramatically during Trump’s first year in office.... The United States led the small pack of countries that managed to lower greenhouse gas emissions, accompanied by UK, Japan, and Mexico. According to IEA figures, the United States managed to reduce CO2 emissions in 2017 by 0.5 percent, or 25 million tons, to 4810 million tons. ... Mr. Wetzel doffed his hat to President Trump,...

    Billions of years ago... our planet’s primordial atmosphere was toxic to life as we know it, consisting of carbon dioxide, nitrogen and other gases. However, by the Paleoproterozoic Era (2.5–1.6 billion years ago), a dramatic change occurred where oxygen began to be introduced to the atmosphere – known as the Great Oxidation Event (GOE). [S]cientists were not sure if this event – which was the result of photosynthetic bacteria altering the atmosphere – occurred rapidly or not. ... Based on newly-discovered geological evidence, the team concluded that the introduction of oxygen to our atmosphere was “more like a fire hose”...

    Fertilisers washing into lakes could increase methane emissions, potentially undoing progress in addressing climate change. The biggest human influence on climate change and global warming is the release of greenhouse gases into the atmosphere. Now research published in the journal Limnology and Oceanography Letters is the first to show how the size of lakes and the nutrients in their waters from fertilisers are contributing to that influence. "Our research pioneers a new way of determining the global atmospheric effect of lakes using satellite information on lake greenness and size distribution," said Professor John Downing. "Our research team assembled the largest...

    Earth’s surface will almost certainly not warm up four or five degrees Celsius by 2100, according to a study released Wednesday which, if correct, voids worst-case UN climate change predictions. A revised calculation of how greenhouse gases drive up the planet’s temperature reduces the range of possible end-of-century outcomes by more than half, researchers said in the report, published in the journal Nature. “Our study all but rules out very low and very high climate sensitivities,” said lead author Peter Cox, a professor at the University of Exeter.

    The concentration of carbon dioxide (CO2) in the atmosphere has hit a new high, the UN said Monday, warning that drastic action is needed to achieve targets set by the Paris climate agreement. “Concentrations of carbon dioxide in the atmosphere surged at a record-breaking speed in 2016 to the highest level in 800,000 years,” the World Meteorological Organization said. “Globally averaged concentrations of CO2 reached 403.3 parts per million in 2016, up from 400.00 ppm in 2015 because of a combination of human activities and a strong El Niño event,” it said. The Greenhouse Gas Bulletin, the UN weather agency’s...

    In 2015, one of the endless subsets of the United Nations – specifically, the United Nations Framework Convention on Climate Change, or UNFCCC – gathered to write a retreat from modernity based on the junk science known as “man-made global warming,” or, more recently, since the discovery of the undeniably fabricated “hockey stick” model that originally justified the idea, “man-made global climate change.” Representatives of 195 countries – yes, that’s almost every country on earth – signed onto the agreement, commonly known as The Paris Accord. In many cases, one representative’s signature was enough, and in others, the signature is...

    The U.S. Environmental Protection Agency's scientific integrity watchdog is reviewing whether EPA chief Scott Pruitt violated the agency's policies when he said in a television interview he does not believe carbon dioxide is driving global climate change, according to an email seen by Reuters on Friday. Lawyers for environmental group the Sierra Club had asked the EPA's Office of Inspector General to check whether Pruitt violated policy when he told a CNBC interviewer on March 9, "I would not agree that it's a primary contributor to the global warming that we see." The EPA Inspector General's office responded to the...

    “If you could pick just one thing to reduce poverty, by far you would pick energy,” Bill Gates has said. “Access to energy is absolutely fundamental in the struggle against poverty,” World Bank VP Rachel Kyte and Nobel Prize Laureate Dr. Amartya Sen agree. The UN Development Program calls energy “central to poverty reduction.” And International Energy Agency Executive Director Dr. Fatih Birol notes that “coal is raising living standards and lifting hundreds of millions of people out of poverty.” In fact, all fossil fuels are doing so.  Indeed, fossil fuels created the modern world and the housing, transportation, other...

    The new chief of the Environmental Protection Agency said Thursday he does not believe that carbon dioxide is a primary contributor to global warming, a statement at odds with mainstream scientific consensus and his own agency. EPA Administrator Scott Pruitt said measuring the effect of human activity on the climate is "very challenging" and that "there's tremendous disagreement about the degree of impact" of carbon dioxide and other greenhouse gases. "So, no, I would not agree that (carbon dioxide) is a primary contributor to the global warming that we see," Pruitt told CNBC's "Squawk Box." Pruitt's view is contrary to...

    Cement, the ubiquitous material used to build roads, buildings and other infrastructure, absorbs about one billion tons of atmospheric carbon dioxide (CO2) annually, according to a new study published Monday in the journal Nature Geoscience. But concrete carbonation is “not currently considered in emissions inventories” kept by the U.N. Intergovernmental Panel on Climate Change (IPCC), according to the study’s co-authors, an international team of researchers led by Professor Dabo Guan of the U.K.’s University of East Anglia. The study found that cement’s natural carbonation process not only offsets the fossil fuel emissions released during its production, it also “represents a...

    Geneva (AFP) - The concentration of carbon dioxide (CO2) in the atmosphere has passed an ominous milestone, ushering the planet into "a new era" of climate change, the UN said Monday. For the first time on record, the amount of CO2 in the atmosphere averaged 400 parts per million (ppm) in 2015, the World Meteorological Organization (WMO) said in its latest Greenhouse Gas Bulletin. CO2, the main greenhouse gas driving climate change, has previously passed the 400 ppm threshold on certain months in specific locations but never on a globally averaged basis, WMO said. The UN agency also reported that...
